An armoured personnel carrier version of the default Jackhammer featuring a vertical stabiliser, 30MM (50MM) Autocannon, .50 Roof Machine Gun, "Shell" Ejection Feature, Troop Compartment Area (Some what based on the BMP-2) and an improved 125MM (150MM) Cannon with a projectile velocity of 850m/s. It also has Pistons for when you get into an ambush position (No idea how to make an auto-brake system, new to Funky Trees). Be sure to empty the shell ejection cannon first before firing and hold longer when firing.

Controls:

Pitch/Roll = Go Forward/Backwards, Left/Right
Turret Elevation = Trim
Turret Traverse = VTOL
Brake = Throttle Down
Pistons = Activation Group 1
Lights = Activation Group 8
Indicator Lights = Activation Group 7
Troop Compartment Hatch = Retract/Extend Landing Gears

Special Thanks to @Adilan for the idea.
More Variants of the Jackhammer will be coming soon!
Feel free to add some suggestions!
